摘要

Abstract

In order to improve land ecological functions classification, explore newclassification methods andprovidetheoretical support, the paper uses the Delphi method to obtain land ecological function score, establishes land ecological function score sheet by setting characteristic factors of acted objects, action mode and effected objects, and carries out the objective classiifcation of land ecological functions by cluster analysis. The study ifnds the analysis effect of the optimal cluster number using semi partial R2 statistic, pseudo-F statistic and pseudo-t2 statisticis better than that using R2 statistic in hierarchical clustering methods. The cluster number analysis effect using Pseudo-Fstatistic is better than that using R2 statisticin K-means clustering method. The classiifcation result by hierarchical clustering is better than that by K-means clustering.
